Hi,
I went with the Scarebird conversion on my 69 Barracuda convertible. I'm half way through the project and so far it's going very smoothly. Although not exactly a kit because you have to gather up all the pieces. With a little careful shopping on Rockauto for close out parts and such the price is coming out quite reasonable and I can keep the original SBP and steel poverty rims. All the required parts are off the shelf items.
